Difference in accuracy or reaction time
researchgate.net
- The Simon effect is the difference in accuracy or reaction time between trials in which stimulus and response are on the same side and trials in which they are on opposite sides, with responses being generally slower and less accurate when the stimulus and response are on opposite sides.

Oct 7, 2020 · In the present study, we review the main theoretical explanations of both kinds of effects and the available neuroscientific studies that investigated the neural underpinnings of the cognitive processes underlying the Simon effect proper and its sequential modulation using electroencephalogram (EEG) and event-related brain potentials (ERP ...
The Simon effect (Simon and Rudell, 1967) refers to the finding that spatially arranged responses to non-spatial stimulus features (such as shape, color etc.) are faster when the task-irrelevant stimulus location and response location correspond compared to when they do not correspond (Leuthold, 2011).
The Simon effect is the difference in accuracy or reaction time between trials in which stimulus and response are on the same side and trials in which they are on opposite sides, with responses being generally slower and less accurate when the stimulus and response are on opposite sides.
In essence, it shows that people respond faster and more accurately if there is a match between stimulus and response features (e.g., location, when for example stimulus and response are both located on the left side of one’s body). The effect is also known as a stimulus-response compatibility effect.
